Definitions

  • the invention relates to a luminaire having a first and a second axis of rotation, via which an optical axis of the luminaire can be aligned.
  • the invention further relates to a lighting system with a luminaire and light source (s) according to the invention.
  • Radiators are known from the prior art, which are usually arranged on a support element via a vertically oriented arm.
  • This arm defines a first vertical axis of rotation about which the radiator head can be rotated.
  • the radiator head is usually connected to the arm via a joint, so that a second, horizontal axis of rotation is formed, as a result of which overall alignment of the radiator head and thus alignment of the optical axis for the light emission can be achieved.
  • the lamp head has to be greatly influenced in terms of its orientation and appearance. With several luminaires located on a ceiling, this sometimes results in a very restless ceiling appearance.
  • a luminaire for the illumination of rooms which has a first luminous element, which is arranged pivotably about a first axis, and a second luminous element which is pivotally mounted about a second axis.
  • the EP 2 128 516 A2 discloses a radiator in which a main body can be aligned about the axis of a first arm and about the axis of a second arm.

  • the solid angle range preferably results from the sum of the points of intersection of the optical axis with an imaginary plane or surface.
